Complainers seem to be very unhappy people inside. There’s a lot that they don’t like about themselves. Things will always be wrong or only half right and could be done better their way. They see life differently than others. I guess. If they spend all their time complaining about you, it takes the focus off of themselves. There will never be anything that you can do to please a complainer. Sometimes the complaining is about a whole different problem.
Complainers have somewhat of a control issue. Everything they say is more important than what you have to say to them; Very judgmental and quick to point a finger.
Common Sense Solution: Invest in Ear Plugs; do everything they say; get Counseling Or Leave.
